cnocn Specification of Iietters Patent. Patgnllygfl Dqg, 41L, 1191'?Application filed May 7, 1917. Serial No. 166,811.

To all whom it may concern:

Be it known that I, FREDERICK S. TYSON, a citizen of the United States,residing at Lock Haven, in the county of Clinton and State ofPennsylvania, have invented certain new and useful Improvements inChocks, of which the following is a specification. f

My invention consists of an improved chock. One object of my inventionis to provide a chock which will be particularly adapted for thetransportation of automobiles and other vehicles in railroad cars,boats, etc.

Another object is to so construct my in vention that the weight of thevehicle resting thereon will serve to increase the frictional engagementof the chock with the floor upon which it rests.

A further object is to so make my invention that it will be durable andof simple construction.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which Figure 1 is a side view of myinvention showing a vehicle wheel resting thereon.

Fig. 2 is an enlarged section on the line 22 of Fig. 1.

Fig. 3 is an enlarged section on the line 33 of Fig. 1.

Fig. 1 is an enlarged section on the line H of Fig. 1.

Fig. 5 is a perspective view of my invention.

Referring to the drawings, 1 representsmy improved chock which includesa base plate 2, preferably of strap sheet metal which is bentlongitudinally in the arc of a circle so as to conform to the curvatureof a vehicle wheel such as shown at 3 in Fig. 1.

One end of the base plate 2 is turned to provide an eye 1 through whichextends the cylindrical transverse portion 5 of a substantially U-shapedstandard 6. The lower ends 7 of the legs 8 and 9 of said standard arepointed so as to pierce or indent the floor upon which it rests.

The opposite end 10 of the base plate 2 is formed by bending the metalof the base plate downwardly at an angle and T preferably crease andbend the lower end 11 to provide a second standard in which the corners12 and 13 will indent the floor as clearly shown in Fig. 3, it beingnoted that bycreasing the standard 11 as indicated at 14, thecreasedportion w ill'extend to a higherlevel than the corners'l2 and 13,so that only the corners 12 and 13 of the standard 11 will engage thefloor.

T secure a clip 15 to thebase plate 2 by means of two rivets 16 whichhave pointed heads 17 also designed to pierce the floor. The clip 15includes a transversely extending portion 18 and two legs 19 which areformed by bending the material of the clip upwardly above the uppersurface of the plate 2 as shown at 20, and then downwardly as shown at21, so that the free ends 22 of said legs are below thelower surface ofthe transversely extending portion 18 and will engage the floor.

The portions 21 of the legs 19 extend at an angle to the portions 20 andare spaced therefrom as shown at 23. This construction provides aresilient support so that the weight of the vehicle wheel tends both toforce the free ends 22 of the legs 19 into the floor and to slightlyspread the legs. Furthermore, the portions of the legs 19 which extendabove the upper surface of the plate 2, serve as retainers for the tireof the vehicle wheel to prevent lateral movement of the latterrelatively to the base plate.

To further guard against lateral movement and also to prevent a relativerotary movement between the bearing portion of the vehicle wheel and thebase plate, I pro vide two clips 24: and 25. These two latter mentionedclips are similarly constructed and each includes a transverselyextending portion 26 and two angular end portions 27.

Furthermore, these clips are preferably secured by rivets and againstthe under surface of the base plate 2.

By providing a chock constructed in the manner above described, thestandard 6 can be moved into various pivotal positions and the baseplate 2 will accommodate itself to wheels of various diameters.Furthermore, the standards 6 and 11, clip 15, and rivets 17, all serveto frictionally engage the floor in such manner that the weight of theve hicle serves to force said members into the floor and as above notedthe arrangement of the legs 19 of the clip 15 will slightly spread orbow and thereby assist in preventing the slipping of the chock on thefioor.

My invention is of comparatively simple construction, is durable, andefficiently performs its work. c

lrVhile I have described my invention as taking a particular form, itwill be understood that the various parts of my invention may be changedWithout departing from the spirit thereof, and hence I do not limitmyself to the precise construction set forth, but consider that I amat'liberty to make such changes and alterations as fairly come withinthe scope of the appended claims.

,Having thus described my invention, what I claim, as new and desire tosecure by Letters Patentis: I i r 1. A chock for vehicle wheelsincluding an arcuate base plate made or sheetmaterial and having anqeyeformed at one end, and a Y standard having a portion rctatably mountedin said eye, said standard also having a free end portion adapted toengage thefioor, substantially as described.

2. A check for vehicle wheels including an. arcuate base plate and legssecured to said plate, said legs having portions extending above andbelow the plate, said upwardly extending portions providing clips toprevent lateral movement of a wheel on the plate, said downwardlyextending portions being adapted to pierce the floor and prevent lateraldisplacement of the plate, substantially as described.

3. A chock for vehicle wheels including a base plate, a clip, legs onsaid clip extend ing above and below said plate, and a pointed member onsaid base plate between said legs and designed to engage the floor uponwhich the chock rests, substantially as described.

A chock for vehicle wheels including a base plate, a standard extemlingdownwardly from said base plate and being creased to provide sharpcorner poi-l ens "for engagement with the floor, substan all asdescribed.

5. A chock for vehicle wheels including a base plate, a clip, legs onsaid clip 1: ing above and below said plate, 12cc curing the clip to thebase plate and l: h pointed heads designed to pierce the floor uponwhich the check rests, snbst...tiall v described.

In testimony whereof I have signed any name to this specification in thepresence of two subscribing witnesses.
